The "Memory Type" column indicates the type of RAM memory fitted. If there is just a dash present then
the RAM is soldered to the board and not replaceable. Something in brackets indicates that it is replaceable
in some models but not others. Generally the memory form factor is SODIMM. It says DIMM if it isn't.
PC100/PC133 is a 144-pin SODIMM.
PCxxxx is a 200-pin DDR SODIMM.
PC2-xxxx is DDR2 200-pin SODIMM.
I'd
take the actual speed rating with a pinch of salt - I guess what's fitted may be determined by market prices
and I've seen high speed memory fitted in some thin clients that exceeds the capabilities of the in-built
memory controller.
